RALLY ace Jack Monkhouse and his co-driver walked away unscathed from a spectacular 190km/h crash during the Scouts Rally SA at Mt Crawford on Saturday.

SA rally and stunt driver Monkhouse, now based in Sydney, and navigator Darren Masters were cleared of serious injury after Monkhouse’s Nissan Silvia rolled mid-air at high speed and bounced off two trees before bursting into flames.

The pair was racing the second day of the 2014 Scouts Rally SA when a rock on the crest of a rise threw the car off balance, sending it rolling in the air at an estimated 190km/h.

The car landed on its roof, before hitting a tree front-on and bouncing backwards into another tree.

Both men were able to free themselves from the wreck and were cleared of serious injury at the scene. They were taken to Angaston and District Hospital for official review, under strict Australian Rally Championship procedure.

The modified Nissan Silvia, worth $80,000, was destroyed by the fire despite a rapid response from emergency teams.

Monkhouse’s father Bill, also competing in the event and a long-time emergency department doctor, said his son’s only real injury was a bruised ego.

“He’s smoked the deposit on his house and the ego has taken a beating,” Dr Monkhouse said.

“He only got burnt on his ankle when he went back to try to get his phone and wallet, but otherwise he’s okay.

“Thank the Lord that we don’t scrimp on any of the safety stuff. It’s not lucky — it’s the effort we put into those cars.

“That’s my kid, I build the cars and I won’t let anyone else build them. There’s no way he’s going to get hurt in one of my cars.”

Monkhouse is the lead driver in the popular Team D-MAX Precision Driving Team that performs at national events including the Royal Adelaide Show.
